Low Earth Orbit (LEO) refers to the region of space extending from about 160 to 2,000 kilometers above Earth's surface. This zone is commonly used for satellites, including those for communications, Earth observation, and scientific research. LEO offers advantages such as lower latency for data transmission and reduced launch costs compared to higher orbits. However, satellites in LEO move quickly relative to the ground and require frequent repositioning or replacement. Many modern satellite constellations, like Starlink, operate in this region to provide global internet coverage.
